Organic compound fertilizer prepared from gadfly feces and application of organic compound fertilizer

Abstract

The invention provides an organic compound fertilizer prepared from gadfly feces and application of the organic compound fertilizer, and belongs to the technical field of fertilizers. The organic compound fertilizer comprises the following raw materials in percentage by weight: 55%-80% of gadfly manure, 10%-25% of chicken manure organic fertilizer, 5%-15% of agricultural rare earth, 0.5%-2.5% of potassium nitrate, 0.3%-0.7% of calcium magnesium phosphate fertilizer and 1.5%-5% of matrix. The special compound organic fertilizer is prepared by taking the gadfly dung as a main raw material according to elements and fertilizer requirements required by growth of fruit trees, is rich in organic matter content and reasonable in element ratio, has the characteristics of increasing the fertilizer utilization rate, improving soil properties, promoting root development and the like, meets the requirements of the fruit trees in a flowering period and a fruiting period, can remarkably improve the fruit quality, and achieves the high yield and high quality of fruit trees.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an organic compound fertilizer prepared from horsefly manure and its application. Background technique [0002] Long-term application of chemical fertilizers can easily lead to the inability of nutrients to be effectively absorbed and utilized by crops. Some chemical substances such as nitrogen, phosphorus, and potassium are easily consolidated by the soil, forming various chemical salts, and accumulating in the soil, resulting in imbalanced soil nutrient structure and changes in physical properties. Poor, some plots of harmful metals and harmful bacteria exceed the standard, leading to deterioration of soil properties. Long-term excessive application of nitrogen fertilizer will also cause the loss of calcium, magnesium and other elements, which will continue to acidify the soil and eventually lose productivity. The application of chemical fertilizers will also l...
